Description

The OMNIBUS F4 Flight Controller is a feature-dense autopilot built around the STM32 F405 microcontroller, delivering the processing power required for advanced Betaflight flight modes and filtering. Its integrated AB7456 OSD chip allows pilots to configure and display critical flight data like battery voltage, current draw, and RSSI directly on their FPV goggles without external modules.

Electrical design includes a robust 7-21V input range, accommodating 2S to 5S LiPo batteries, and a built-in 5V/2A BEC to power receivers, VTXs, and cameras. The onboard MPU6000 IMU and BMP280 barometer provide accurate attitude and altitude data, while the microSD slot enables detailed black box logging for tuning and post-flight analysis.

Key Features

  • High-performance STM32 F405 MCU with 168 MHz clock speed and floating-point unit.
  • Integrated AB7456 OSD chip for customizable, low-latency telemetry overlay.
  • Built-in current sensor and 5V/2A BEC for streamlined power management.
  • MPU6000 gyroscope/accelerometer and BMP280 barometer for precise flight control.
  • MicroSD card slot for high-rate black box data logging.
  • Wide receiver protocol support: S.BUS, S.BUS2, DSM2/DSMX, PPM, Graupner SUMD.
  • Compact 36x36mm PCB with standard 30.5x30.5mm mounting hole pattern.
  • Direct Betaflight and iNav firmware compatibility for versatile configuration.

Applications

  • 5-inch FPV racing drone builds requiring integrated OSD and black box logging.
  • Freestyle quadcopters utilizing Betaflight's advanced filtering and rates.
  • DIY drone projects needing a compact FC with built-in power regulation and current sensing.
  • Long-range or endurance builds leveraging the BMP280 barometer for altitude hold modes.

Frequently Asked Questions

What is the input voltage range for the OMNIBUS F4 Flight Controller?

The controller accepts a wide input range of 7V to 21V, making it compatible with 2S, 3S, 4S, and 5S LiPo battery packs. The onboard 5V/2A BEC provides clean power for your receiver, VTX, and camera, eliminating the need for an external regulator.

How do I set up the On-Screen Display (OSD) with Betaflight?

Connect the FC's video in/out pads to your camera and VTX. In Betaflight Configurator, enable the 'MAX7456' OSD device type. You can then use the OSD tab to drag, drop, and configure telemetry elements like voltage, current, timer, and RSSI directly onto your FPV video feed.

Does this flight controller support black box logging, and what is required?

Yes, it features a microSD card slot for black box logging. You need to insert a formatted microSD card (FAT32). In Betaflight, enable black box logging and select the appropriate logging rate. This records detailed flight data for analyzing motor performance, gyro noise, and tuning filter effectiveness.

What receiver protocols are supported by the OMNIBUS F4?

It supports a wide array of protocols via its UART ports, including S.BUS, S.BUS2, DSM2, DSMX, Graupner SUMD, PPM, and Yuneec ST24. Ensure you solder your receiver's signal wire to the correct UART RX pad and configure the corresponding serial RX setting in Betaflight.
